Community and social computing

I tried the MIT Personas site just to see what it would come up for my
name. Basically, it does a Web search for any name you give it and
analyzes the text on a semantic level to find common themes or
categories for content from you or about you (e.g., it might suggest
topics like "sports", "legal", "social", "management", "online", etc.)
How it does this is a little beyond my knowledge of semantic
processing, as well as what practical use this is seems to escape me.

But it's fun. :)
Some issues with it, is that because it searches on people names across
the Web, the content may mistake e.g., one "Luis Suarez" (our own
blog-evangelist) with another "Luis Suarez" (soccer player). It helps
if you have a globally unique name like "Rawn Shah" (so far). Another
problem is that the results may vary depending on how it processes
whatever search results it finds. So, in trying it out three times to
see how close it was, it showed slightly different categories for me
and sized these differently as well.

I can't figure out why the following categories appear since I rarely if ever talk about them: military, religious, religion, genealogy
